I just realised I almost forgot to post my own thing But here it is. It's a recipe for Vanillekipferl, some classic German christmas biscuits. They are really easy to make.
You need: 300g flour 250g butter 125g sugar 3 egg yolks 125g ground almonds 15g vanilla sugar I don't really know if vanilla sugar exists in other places or not. It's just sugar that has been put in a place together with vanilla for some time, so it tastes a bit like vanilla. It would be too late to make that yourself if you want to bake the things before christmas, so I suggest you just take a little bit of something which tastes like vanilla (and isn't artificial if possible) and mix it with a bit of sugar.
Just mix everything except the vanilla sugar together and put it in some half-circle shape. Of course you can make any other shape too if you like. Then put it in the oven with 175-195°C for about 10 minutes, until they look as baked as you want. Dip the top side in the vanilla sugar while they are still hot. You can also put some cocoa powder or cinnamon there if you want. This is what the things look like:
Another idea is to just make small circles/bowls and then press the middle down to create a kind of pit, and then you can put jam or chocolate or whatever you want in there. The ones in this picture kind of failed, but you get the idea:
